CHAIR..

Application led January 25, 1924.

My invention relates generally to improvements in chairs, but relates more particularly to improvements in so called tablet arm chairs.

The general object of my invention is t0 provide a tablet arm chair which shall'be of such construction that it can be adjusted to meet the individual requirements oit the user and still maintainthe proper relation of the parts t'or most comfortable use.

I aim also to provide a'tablet arm chair Construction of simple, strong and durable form and in which the back rest and tablet arm shall both be adjustable in order better to fit the individual characteristics of the user. j

My invention consists generally in a tablet arm chair ot the form` arrangement, construction and the co-operation of the parts thereof, whereby the above named objects, together with others that will appeal1 hereinafter, are attainable, and my'invention Will be more readily understood by reference to the accompanying drawings which illustrate What I consider at the present time to be the preferred embodiment thereof.

In said drawings:

Fig. 1 is a side elevation of a chair embodying my invention;

Fig. 2 is a detail fragmentary front vien7 taken substantially 'along the line 2-2 of n Fig. 1;

Fig. 3 is a detail sectional View upon an enlarged scale taken substantially along the line 3-3 of Fig. le; and

Fig. 4 is a detail sectional View, on an en larged scale, substantially along the line 4% of Fig. 3;

The exemplary chair here shown comprises the metal legs 1 which are suitably connected by braces 2. The chair seat 3 in this instance, is carried upon a chair frame composed of front and rear strap members 4 and 5 and the side The chair is provided with a back rest 8 which in turn is swingably carried in arms 9 which upstand from the metal seat frame and are secured thereto by means of bolts 10. The arms 9 are suitably braced by means of the curved braces 1l Which are secured to the seat frame by means of bolts 12 and to the arms 9 by means of the loose rivets 13. The arms 9 and the seat frame side members 6 and 7 are provided respectively With a plurality ot holes 14 and 15 so that the supported in a novel manner.

angularposition of the back may be adjusted, one such adjusted position beings'hown in Fig. lby means ot dotted lines. j

A tablet arm or table-like member 16 is Thus atV its rear endit is supported by a strapmetal member '.17 Which is secured to the bottom ot' the tablet arml as by meanso'l screws 'or other fasteningdevices 18, andthe end portion 19 is twisted at an angle so that' it presents fiat face to the arm 9" to Which itis loosely riveted or otherwise securedto'permit oi the necessary swinging movement,'as indicated at 20. f

At thetorivard end or part the tablet arm is supported by a standard 21 which is "suitably secured" to the seat supportingframe as indicated at 22 and 23. The standard 21"in this instance is in the form of a metal tube u'hich terminates in close proximity tothe `Overl the top Yot the tube I secure a vU-shaped metal clip or member 24 which is secured firmly in place as 'by means ot rivets 25. The'edges 26 and 27 otl the'elip24'form good bearings for the t'ace portions of the fangle members 28 and y29With respect to Which'tlieylare relatively movable. The angle members `28 and 29 'are firmly securedto the under face of the'itablet arm, as byfastening devicesd30.

The depending spaced portionsbt themembers 28 and 29 are provided With a plurality of aligned holes 31l and a bolt 32 j passes through a pair thereof and through an opening 33 provided in the standard 21 and the encompassing U-slip 24. Byfthis means the tablet arm is the front support and yet it is so arranged that proper adjustment can be made to accommodate the movement. Which'takes place as the back rest is adjusted rearward Orfor- Ward, to the individual user. The flat surfaces of the edge portions very rigidly attached to v i requirements of the of the U-clip cooperate With the angle members 28 and 29 in providing a construction which firmly resists the racking action to which the tablet arm is peculiarly subjected in use.

The many advantages of'my chairfwill now be understood vby those skilled `inthe art to which this appertains Without further comment.
